Adding ReplayGain tags

[w3wilkes]

Did the bulk file changer and copied the Modified time stamp to the Accessed time stamp, ran foobar2000 to do track gain and then album gain. Looks like I've now got RG for Albums and Tracks with album peaks and track peaks. Looking at the files I see that foobar2000 preserved the Modified time stamp so now the Accessed and Modified timestamps are the same which I don't see as a big deal. Couldn't find any documentation on foobar2000 leaving the Modified timestamps alone! Anyone have any info on that?

I can’t remember exactly as it was a fair while ago that I did it but I ran Foobar2000 over my entire library to add RG tags in conjunction with Bulk Filechanger and I ended up with the desired result. That said I did it in a few lumps as conveniently I had 3 top level folders.

I don’t run LMS on Windows but I expose my music files via Samba so it’s effectively the same

I just use metaflac to add replay gain.
This script I use will work (FLAC files only) IF you have your files organized by Artist/Album (where each album has its own folder) (not sure how else it could/should be organized)

This script will walk the directory entered in the FIRST line. My files are in ~/Music/FLAC, so starting there will process all FLAC files.

If you want to use this, test on one Album (or Artist) first:

#!/bin/bash

StartDir=$HOME/Music/FLAC	# No trailing slash!
count=0

function walk_tree {
	local directory="$1"
	local i
	for i in "$directory"/*
	do
		if [ -d "$i" ]; then 	# Process directory and then walk-down
		ls "$i/"*.flac | grep -i -q -s ".flac$"	# Does directory contain FLAC files?
		if [ $? -eq 0 ] ; then
			echo "Adding replay gain tags to:"
			for j in "$i/"*.flac
			do 
				echo "$j"
				let count++
			done	
			/usr/local/bin/metaflac --preserve-modtime --add-replay-gain "$i/"*.flac
			echo "$i done!"	# echo directory that we're in
			echo $count files processed.
		fi
		walk_tree "$i"		# DO NOT COMMENT OUT THIS LINE!!
		else
			continue		# replace continue with command to process individual file "$i" (i.e. echo "$i")
		fi
	done
}

# Process FLAC files in starting directory
cd "$StartDir"
ls *.flac | grep -i -q -s ".flac$"		# Does directory contain FLAC files?
if [ $? -eq 0 ] ; then
	echo "Adding replay gain tags to:"
	for j in *.flac
	do 
		echo "$j"
		let count++
	done	
	/usr/local/bin/metaflac --preserve-modtime --add-replay-gain *.flac
	echo "$StartDir done!"	# echo directory that we're in
	echo $count files processed.
fi
# Now walk down tree in this directory
walk_tree "$StartDir"
